The objectives of this research project are to: (1) study sediment and phosphorous loadings from the land surface to the Cannonsville Reservoir in Upstate New York; and (2) investigate the role of uncertainty in the calculation of these watershed loadings. The analysis will focus particularly on spatial uncertainty, such as spatial distribution of rainfall data and topographical information.
The approach of the evaluation of the Best Management Practices (BMPs) and land use practices is to develop a basin-wide watershed model for the Cannonsville Basin. The model simulates hydrology, sediment, and phosphorous transport over the watershed, which ultimately becomes an input to the reservoir. The model being applied is the Soil and Water Assessment Tool, which was developed in Texas for use on agricultural lands. This model, which will be combined with geographical information systems (GIS), is spatially distributed, requiring that the entire basin be divided into smaller subbasins of similar land use, soil properties, and topography.
Using GIS, meteorological data, river geometry information, and constituent parameters, the model will develop the fate and transport of phosphorus and sediment over the land surface.
